Just to throw an idea that no one has touched on. How does a trainer (either in-house or outside) become adept in training with actual in the seat experience on forklifts fitted with attachments beyond a basic side shifter or fork postioner - attachments like paper roll clamps-single & double roll handlers, carton clamps, tire handling attachments, container handling top lifts, single/double block handling, marble/granite handling, single /double reach, basloid (single/double)etc.??
Obviously, it would be difficult or very highly unlikley to find a trainer that would have had experience on 3 or 4 of the multi function (some with 5 functions) attachments that Cascade, Balzoni, Long Reach, etc offer.
